安装python parsley时出错

Question

我正在尝试安装parsley，这是一个用python编写的解析器，但我遇到了第一个障碍。我甚至不能安装它。我用的是windows7，使用cygwin。

这个版本的python：$ python3 -V Python3.4.2

$ pip install Parsley

  Running setup.py (path:C:\cygwin64\tmp\pip_build_ds\Parsley\setup.py) egg_info for package Parsley

Successfully installed Parsley
Cleaning up...

然后在python的空闲状态下：

>>> import parsley
Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    import parsley
  File "C:\Python34\lib\site-packages\parsley.py", line 86
    except ParseError, e:
                     ^
SyntaxError: invalid syntax

我做错了什么？

Parsley (目前为1.2)不支持Python3.x。

您需要使用Python 2.x才能使用该包。
